The undersigned, Eric S. Rangen, hereby authorizes and designates
each of Marianne D. Short, Dannette L. Smith, Richard J. Mattera and
Amy L. Schneider, or any of them, acting singly with full power of
substitution (each, an "attorney-in-fact"), to sign and file on the
undersigned's behalf the Form ID in order to obtain or manage EDGAR
filing codes, and any Forms 3, 4, 5 or 144 (including any amendments
thereto) that the undersigned may be required to file with the
Securities and Exchange Commission as a result of the undersigned's
ownership of or transactions in securities of UnitedHealth Group
Incorporated (the "Company") at any date following the date hereof.
The authority of each attorney-in-fact under this Power of Attorney
will continue until the undersigned is no longer required to file

or transactions in securities of the Company, unless earlier revoked in
writing.  The undersigned hereby revokes all previous powers of attorney

regard to Company securities as of the date hereof, except that if the
undersigned has adopted any Rule 10b5-1 trading plan to transact in
Company securities, any powers of attorney the undersigned may have
granted under the plan to sign or file on the undersigned's behalf any
Form 144 shall continue to be in full force and effect in accordance with
the terms of the plan.  The undersigned acknowledges that neither the
Company nor an attorney-in-fact are assuming any of the undersigned's
responsibilities to comply with Section 16 of the Securities Exchange
Act of 1934 or Rule 144 under the Securities Act of 1933.
